Seven For All Mankind – one of the most well known high-end denim lines – has just opened a 5,000-square-foot flagship in Tokyo in a spot that once housed a Nicole Miller boutique.

The shop is located in a trendy shopping and cafe area called Daikanyama. The megastore will carry Seven For All Mankind womenswear and menswear denim, sportswear, and accessories.

Seven president Topher Gaylord noted that Japan is the number-one market in Asia and that it’s a critical market for the luxury denim line, adding – “we believe now, in this period, there is an incredible opportunity for strong brands…to build upon their position. Asia is going to be our fastest-growing region of the world for Seven For All Mankind in 2009.”

In addition to this Tokyo opening, another 30 to 35 Seven stores are slated to open this year in Asia. Anticipated locations include Hong Kong, Taiwan, Shanghai, Beijing, Singapore and Kuala Lumpur, Malaysia.
